What are you thinking? You’re already on probation and you’ve lost custody of baby Jace — why would you risk jail time, by being seen with beer!

Jenelle Evans, 19,was spotted on the beach with a male friend on April 21 at Yaupon Pier in North Carolina and there was beer on the blanket! Her lawyer insists the Teen Mom star was NOT drinking.

Just because her mom Barbara cares for her baby Jace, don’t you think Jenelle should be more careful about appearances? Her attorney tells TMZ.com that Jenelle wasn’t “engaging in any illegal alcohol consumption.”

Between this beach scene and the caught-on-video beatdown she delivered to another teen mom in North Carolina, doesn’t it seem like Jenelle is making all of the wrong moves lately?
